    Add a new cgroup freezer selftest, which checks that if a cgroup is
    frozen, their new child cgroups will properly inherit the frozen
    It creates a parent cgroup, freezes it, creates a child cgroup
    and populates it with a dummy process. Then it checks that both
    parent and child cgroup are frozen.
